## The honest read

Dean Farnham Plumbing & Heating is a South Dennis shop the Better Business Bureau lists as a 24-year, A+-accredited plumbing and heating business, handling everyday work like drain clearing and water heater installs alongside gas piping, gas appliance installation, and radiant-heat systems. Its Massachusetts plumbing master license, held by Dean P Farnham, is active. Angi and HomeAdvisor's profiles for the company also list free estimates and NFIB membership.

The written history here splits into two very different chapters. In a run of Angi reviews from 2011 to 2016, customers described Dean as fast and reliable: a 2016 review recalls him returning a call about a leaking water main and arriving within the hour on New Year's Day, and a 2014 review describes him diagnosing and fixing a gas leak behind a customer's dryer within a couple of hours of National Grid flagging it. A 2012 review credits him with a clean, correctly done Rinnai water heater install at a fair price, and several others from that stretch mention punctuality and fair pricing on the Cape. A separate 2014 review broke that pattern, citing poor communication and promised dates that never materialized.

Then the trail goes quiet until 2025, when three new one-star reviews appeared — two on Google, one on Angi — calling the owner unprofessional and untrustworthy. Google's own rating now sits at 2.3 stars from three ratings, while Angi and HomeAdvisor still carry the older 4.1-star profile built on that longer history, and Porch shows 4.7.

Worth asking about directly is what's behind the 2025 complaints, and getting a written quote and start date up front given the 2014 communication complaint on file.

Dean Farnham is a licensed, BBB-accredited South Dennis plumber with a deep history of emergency and gas work through the mid-2010s — a reasonable call for plumbing and heating jobs, but worth a quick gut-check on current responsiveness before booking anything time-sensitive.

**Strengths:**
- Licensed plumber — Massachusetts plumbing master license is active
- BBB accredited — A+ grade after 24 years in business
- Prompt emergency response — recurring praise in Angi's 2011–2016 reviews
- Fair pricing — repeated mentions in early Angi reviews

**Concerns:**
- 2025 one-star reviews — two on Google, one on Angi call service unprofessional
- 2014 communication complaint — one review cites missed promised dates

**Where sources disagree:**
- Google's 2.3-star aggregate from three ratings runs well below Angi and HomeAdvisor's shared 4.1-star profile and Porch's 4.7-star listing, reflecting how much more recent Google's activity is
